I don't have an answer for you, but was hoping you would know how common factory or dealer installed A/C was in the 2002 or 2002tii models from 70-74? How effective was it in keeping the cars 'comfortable'? In today's resale market what is the likelihood of finding one with factory A/C?
In the early 70's our family owned a 6 cylinder Bavaria and the factory A/C could barely keep the 'green house' sedan cool in the summer months.

Yeah, no question about the "drag" of AC on a 2002 engine. But I would think some of the newer Japanese compressors are way more efficient than what was original equipment (yuk).
Thanks for the tip, m4dzl.

I am doing a complete restoration on a 75 02 that had the dealer installed air on it, after doing some research I am not going to put it back in the car. The old York compressors vibrate a lot, I found worn bolts, stripped threads and cracked mounts, using the old R12 freon with R134a, the only thing you can use now, the head pressures are higher = MORE VIBRATION . So you would need to use a modern rotary compressor and make a mount for it , then the next problem R134a is not as efferent as R12 was so you need a bigger evaporator and condenser, there is no room in front on the 2002's radiator to install a larger condenser than the one it had ,which is about 1/3 the size of a new car using R134a. So after you would spend all the cash to try and change things around and with all the glass the 2002 has I don't think it would be worth the results which would not be as good as when the air was installed in 1975 and not even close to a late model cars air. What do you think?
